TH8986EX - Methods and systems for cleaning solvents - Google Patents

Abstract

Cleaning methods and cleaning systems using organic solvents such as Freon The cleaning tank (1) is closed after the workpiece (2) to be cleaned is placed inside the cleaning tank. The cleaning tank (1) has a concave bottom wall (60), receives the ultrasonic oscillator (11), the solvent is fed into the cleaning tank (1) from the solvent storage tank. (3) The workpiece is cleaned by itself. Melt that entered After cleaning The solvent was It is released in the liquid state from the cleaning tank (1) while the solvent vapors remaining in the cleaning tank are released. To the condenser (16) to condense the vapor The condensed solvent is returned from the condenser (16) back to the solvent storage tank (3). The liquid and the vapor solvent was released from the cleaning tank (1) and the cleaned workpiece was removed from the tank. For cleaning Before the cleaned workpiece is brought out, air is fed into the cleaning tank (1), at least at the end of the vapor discharge phase of the The condenser (16) is integrated into the distillation apparatus (14), the solvent vapor dosing unit (34) is connected to the cleaning tank (1). Freon into the atmosphere

Claims (1)

1. Method for cleaning the workpiece with solvent Consists of the steps of Closing the cleaning bin (1) after the workpiece (2) to be cleaned is placed inside the cleaning bin. Feeding of solvent into the stake cleaning tank from the solvent collecting tank (3) reaching the air from the cleaning tank (1) cleaning the workpiece to be cleaned with solvent. That is fed after the air is extracted from the tank (1). Solvent release in the state The liquid from the cleaning tank (1) enters the solvent reservoir.
